' Be it knownthat I, LoJos Boo-NA a subjectjof the'King of Hungary, residing at VVl1iting,.in the county of Lake and State of Indiana, have invented certain new and useful Improvements 1n Aerial Vessels, of

' which the following'is a specification, reference being had therein to the accompanying- 7 drawing. 'This'invention relates to aerial vessels of v the 'dirigible type, and has for its object to provide avesselgof such class, in a manner ashereinafter'set forth, for reducing the resistance to a minimum of the body of the 5 vessel to the atmosphere during the travel of the vessel.-

, A furtherobject of the inventibn to prov-ide avessel .of the class referred to, with means in a manner as hereinafterset forth,

forefiiciently steadying the vessel during the travel thereof.

, I Further, objects of the inventionare to .provide a vessel of the class referred to.

which comparatively simple in its conzbstruction, strong, durable, conveniently steered, readily set up and comparatively inexpensive to build. Q I, WVit-h the foregoing and other objects in Q view,'the invention consists of the novelcon-U struotion, combination and'arrangement of parts as hereinafter more specifically de- 2 scribed. and illustrated in the accompanying i draw-i-ngs, wherein is shown an embodiment i ofthe invention,

'1 can be resorted to which come within the p but it isto be understood that changes, variations and modifications scope of the claims hereunto appended.

In the drawings, wherein like reference characters denote corresponding parts throughout the several views :-F .;-ure 1 1s a side elevation, broken away. in parts, of an aerialvessel constructed in accordance with this invention, Fig. 2 is a perspective view of the hull of the vessel, Fig. 3 is a cross sectional view on line Fig. ,1, looking in the direction of the arrows, 4 is a sectionion line Y'Y Fig. 1 looking in the direction of the arrows,"Fig '5 is a top plan View of the vessel, and Fig. 6 is a front eleation.

Referring to the drawings in detail, the. vessel includes a hull 7, which is 'substan-' tially V-shaped in vertical section and is provided with asharp keel 8 and a pointed 5 prow.9, which projects forwardly'from the hull. In plan the top of the hull gradually portion.

decreasesin width from frontto rear as at' l0, and said hull 7; gradually decreases in height from frontto rear whereby when the F vessel is set up and traveling, the hull, will extend forwardly and downwardly at an incl nation. The vessel further includes. a

buoyant body portion, which is substantially of cigar-like form, and the said body portion comprises a lattice work frame 11, inclosed bya flex ible cover 12. Each end of the body portion is closed asat 13 and 14, and each of the said ends of said body'portion is pointed. I

The body portion can be inflated by air or gas and suitable; means, not shown,'is provlded to permitthe inflationof said body The lattice work frame 'supportsa pair of rearwardly extending; propellershafts 15 and 16and suitable bearings are provided in the lattice work; 11 for supporting said shafts 15 and 16. The shafts 15 and 16 pro-' ject' outwardly ,from and rearwardlywith respect to the said buoyant body, and each of said shafts has its rear end provided with a, plurality of propeller blades 17.

Fixed to, each of the propeller shafts is a' cog wheel 18,-'which is engaged byfa c'og' chain 19 for driving the shaft and said cogchain 19, extends down' and into the hull and 1s driven from-an engine shaft 20." The engine shaft 20 projects'forwardly and rearwardlyv with respect to the" engine 21- and i the rear portion of: the shaft 20, as above stated, is operatively connected with the cog, chains 19, while the forward portionof the shaft 20 is operatively connected by the-driving elements 22with a pair of forwardly projecting steering propelling shafts 23. The shafts .23 have their forward ends provided with propeller blades 24,, and the said forward ends of the said shafts 23 project forwardly from the prow 9 of the hull 7.

The hull 47 has depending therefrom brackets 25, carrying the axles 26, provided with wheels 27 to proyideforportability .of the vessel when upon the ground.

The buoyantbody is connect d to the top of a hull 7, by coupling means 28, which as. illustrated consists of loops of wire or rope and which are connected through the covering 12 with the frame 11, and furthermore extend through openings 29', in the topof the hull 7.

Mounted upon the top of the buoyant body in proximity tothe rear end thereof,

is a frame 30, which is connected centrally I I of the lower portion thereof with the buoyant body and connected to the top of said frame 30 is a'fiexible steadying'plane 31.

} Mounted upon the top of the buoyant bodyin proximity to the front end thereof "is a supporting frame 32 and which is mounted centrally of its lower face upon the top of the buoyant body and the said frame 32 has the top thereof provided With a flexible steadying plane The plane 33 is braced through the medium of cross members 34 which are secured to the frame 30 and to the-upright member 35, carried centrally of the top of said frame 30, and the said plane33' 1s reinforced through the medium' 7 ofbr'acemembers 36. Secured to the frame 1 32 is an upright member 37 carried centrally of the top of the frame 32. The brace members 36 cross each other.

Theframe 30 is connected to the hullby inclined braces 38 and the frame 32 is also connected to-the hull by inclined braces 39.

c -jThe frames 30 and 32 are of materially I greater length than the larger diameter of the buoyant body and the said frames project laterally. from each side of said body. The buoyant,body is so shaped as to reduce resistance-to a minimum during the travel of the vessel through the air and the construction of the hull also reduces resistance to 'a minimum during the travel of the vessel.

What I claim is 1. An aerial vessel comprising a hull hav' ing a pointed prow and being substantially vV-shaped in cross section, said hull gradually decreasing in height from its bow to itsstern and further having the top thereof gradually decreasing-in width from its bow to its stern, a cigar-shaped buoyant body mounted upon and secured to said hull and having the smaller portion thereof'projecting rearwardly from the stern of the hull,

steadying planes mounted upon and secured ing a pointed prow, a buoyant body gradu ally increasing in diameter [from its rear toward its forward end, of greater length than said hull, said body mounted upon and secured to said hull and projecting rearwardly' from'the stern of the hull, driving propellers supported from said body, steer ing propellers supported forwardly of said hull, and means arranged in said hull and op eratively connected withsaid driving and steering propellers for operating them.

3. An aerial vessel comprising a hull substantially V-shaped in cross section and having a pointed prow, a buoyant body gradually increasing in diameter from its rear toward its forward end, .of greater length than said hull, said body mounted upon and secured to said hull and projecting rearwardly from the stern ofthe hull, driving. propellers supported-from said body, steering propellers supported forwardly of said "hull, means arranged in said'hulland operatively connected wlth sald driving and stecring propellers for operating them, and a plurality of steadying planes mounted upon and extending transversely with respect to said body.

l. An aerial vessel comprising a hull substantially V-shaped in cross section and having a pointed prow,a buoyant body gradually increasing in diameter from its reartoward its forward end, of greater length than said hull, said body mounted upon and secured to said hull and projecting rearwardly from the stern of the hull, driving propellers supported from said body, steering propellers supported forwardly of said hull, means arranged in said hull and operatively connected with said driving and steering propellers for operating them, and

a plurality ,of steadying planes mounted upon and extending transversely with re spect to said body, saidplanes arrangedone in advance of the other and the forward plane being of greater length than the rear plane.

In testimony whereof I ailix my signature in the presence of two witnesses.
